An algorithm on automatic topology discovery in OpenFlow supported software defined networks is proposed. The proposed algorithm utilizing link layer discovery protocol allows to obtain the whole network topology by the network controller. We have validated the successful operation of our algorithm through simulation and real network tests seperately, and(More)
In this study, we aim to analyze how Software Defined Networking (SDN) can help to ensure a high-quality uninterrupted Voice over Internet Protocol (VoIP) service accompanied by video for prioritized users and entities in a network congested with background traffic. Guaranteeing a level of Quality of Service (QoS) and resource prioritization are key(More)
This study investigates how Software Defined Networking (SDN) paradigm can be used to ensure high-quality uninterrupted Voice over Internet Protocol (VoIP) service accompanied by video for prioritized users in a network congested with background traffic. Guaranteeing a level of Quality of Service (QoS) and resource prioritization are vital in an emergency(More)
